Display screen or portion thereof with graphical user interface



The FIGURE is a front view of a display screen or portion thereof with graphical user interface, showing my new design.

The dash-dash broken lines in the FIGURE showing the display screen or portion thereof are included for the purpose of illustrating environmental structure and form no part of the claimed design.

The dot-dash broken lines define the bounds of the claimed design and form no part thereof. The area shown with increased opacity between the dash-dash broken lines and the dot-dash broken lines shows environment that forms no part of the claimed design. 

CLAIM I claim the ornamental design for a display screen or portion thereof with graphical user interface, as shown and described.
